Specification of Letters Patent.

Patented J an. 11, 1916.

Application filed January 22, 1914. Serial No. 813,727.

1 b all whom it may concern Be it known that I, VILLIAM H. EVERETT, acitizen of the United States, residing at Mount Pleasant, in the countyof Viestmoreland and State of Pennsylvania, have invented a new anduseful Wrench, of which the following is a specification.

he present invention appertains to wrenches, and aims to provide a noveland improved device of that character.

lt is the object of the present invention to provide a wrench embodyinga novel assemblage of parts wherein the stationary and movable jaws arearticulate with one another, whereby the movement of the handle isemployed for opening and closing the jaws automatically.

Another object of the present invention is to provid a wrench of thenature indi cated, having improved structural features, to render theconstruction compact, durable and efiioient, as well as simple andinexpensive. l

'lVith the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, can be made within thescope of what is claimed, without departing from the spirit of theinvention.

The invention has been illustrated in its preferred embodiment in theaccompanying drawing, wherein Figure 1 is a side elevation of theimproved wrench, portions being broken away. Fig. 2 is a longitudinalsection taken on the line 22 of Fig. 1. Fig. 3 is an end view of thewrench, looking toward the jaws. Fig. 4 is a perspective view, on areduced scale, of the slide and movable jaw carried thereby.

The body of the wrench comprises a pair of spaced cheek or side plates 1having an outstanding integral fixed or stationary jaw 2 at one end oftheir outer edges adjoining certain side edges, as clearly seen in Fig.1.

A fiat slide 3 is disposed snugly between the cheek or side plates 1adjoining and flush with their outer edges and movable adjacent thefixed jaw 2, the outer edge of the slide 3 being equipped with anoutstanding integral movable jaw l slidable upon the outer edges of thecheek or side plates 1 and arranged at that end of the slide 3, oppositethe fixed or stationary jaw 2. slide 3 is curved, and is spaced from theinner edges of the check or side plates 1.

The cheek or side plates 1 are provided with inner transverse grooves orchannels 5 adjoining their outer edges which receive the tongues or ribs6 formed upon the faces or sides of the slide 3 and extendinglongitudinally of the slide, or transversely of the wrench as a whole.The interfitting tongues 6 and grooves 5 guide the slide for sliding orreciprocatory movements, to thereby permit the movable jaw 4 to move toand from the fixed or stationary jaw 2.

A U-shaped reinforcing clip 7 straddles those side edges of the cheek orside plates 1 r at those ends of the outer edges of the cheek platesopposite those adjoining the stationary jaw 2, and is disposed adjoiningthe outer edges of the cheek plates, the terminal portions or arms ofthe clip 7 being secured upon the cheek plates 1 by means of removablescrews or other securing members 8 engaged through the arms of the clipand taking into the cheek plates, whereby the clip 7 will serve tostrengthen and brace those side edges of the cheek plates 1 opposite thefixed jaw 2, which connects the side plates at the corresponding sideedges. The clip 7 also assists in limiting the opening movement of thejaw 4 away from the fixed jaw 2, the end of the slide 3 being arrangedto be received by the clip 7 to arrest the movement of the slide at apredetermined position. When the clip 7 is removed, it will permit ofthe withdrawal of the slide 3 from between the cheek plates, whendesired.

A handle or lever 9, which may be of any suitable length, is pivotedadjoining its outer end between the inner edge portions of the cheekplates 1 at those side edges adjoining the stationary jaw 2, by means ofa pivot 10. Thus, the-handle or lever is fulcrumed or pivoted betweenthe cheek plates at that inner corner adjoining the stationary jaw,whereby the handle when in longitudinal position, as seen in Fig. 1,will practically aline with the stationary or fixed jaw 2. The pivot 10preferably embodies two sections or members detachablv connected bymeans of screw threads, or the like, as clearly illustrated in Fig. 2, aspacing collar or ring 11 being mounted upon the pivot 10 to prop Theinner edge or the erly hold the handle or lever 9 adjoining one checkplate 1. The handle or lever is thus fulcrumed to the stationary jaw,and is articulate with the slide 3 carrying the movable jaw, in themanner which will be presently described. The outer end of the handle 9is provided with a tongue or lobe 12 adjoining one check plate 1, andthe slide 3 is provided in the corresponding side with a recess ordepression 13 receiving the tongue or lobe 12, the recess 13 beingdisposed between the respective tongue or rib 6 and the inner edge ofthe slide, and having a curved wall, as seen in Fig. 1. The slide 3 isprovided, midway between its ends, with an integral lug or pin 14 withinthe'recess or depression 13, while the free or outer end of the lobe 12is provided with an open slot 15 engaging the lug or pin 14:, wherebywhen the handle or lever is oscillated relative to the cheek plates 1,the slide 3 will be given a rectilinear or sliding movement.

For facilitating the gripping of small nuts and other objects by thejaws, the same are preferably provided in their faces with transverseV-shaped grooves 16, which are intended to receive the opposite cornersof the nuts, when the jaws are closed.

In use, when the handle or lever 9 is swung in one direction, to theright, as seen in Fig. 1, the slide 3 will be slid toward the clip 7carrying with it the movable jaw 4, to thus open the jaws for permittingthem to be engaged over a nut, pipe or other object. Then,

when the handle or lever is swung in the other or opposite direction,the slide 3 will be moved so as to force the aw at toward the stationaryjaw 2, to thereby grip the nut, pipe or other object, and at the sametime, a torsional or twisting strain may be imparted to the nut, orother object, for the purposes desired. It will thus be evident, thatthe jaws are automatically opened and closed by the movement of thehandle, thereby avoiding the necessity of adjusting the jaws prior totheir application to an object.

Particular attention is directed to the fact that the operativeconnection between the component parts renders the structure of thewrench thoroughly practical and eflicient, it also being noted that thepivot of the handle or lever is in line with the face of the fixed jaw,whereby when the movable jaw t is midway between the ends of itsmovements, the handle or lever will approximately aline with thestationary jaw, or will lie in the plane of the face of the said jaw,which is desirable. The pivot is not offset from the fixed jaw, as incertain other wrenches of this character, and as a result of thearrangement above described, the handle or lever can be moreconveniently and eiliciently employed for the purposes intended. hen theslide is moved to its extreme position in one direction, or toward theclip 7 one end portion of the wall of the recess or depression 13 movestoward or en gages one side edge of the tongue or lobe 12 to assist inlimiting the movement of the slide and movable aw, and when the slide ismoved in the other direction to close the jaws, the same action willtake place between the other side edge of the tongue or lobe 12 and theother end portion of the wall of the recess or depression 13.

The present device may be employed as a nut or pipe wrench or as a. pipecutter, by properly forming the aws 2 and i, as will be obvious to thoseversed in the art.

Having thus described the invention, what is claimed as new is A wrenchembodying a pair of cheek plates, having an outstanding jaw, a'slidemounted between the cheek plates and having an outstanding jaw, thecheek plates and slide having interfitting tongues and grooves, one sideof the slide having a recess adjacent one cheek plate and a lug or pinwithin said recess, a pivot element engaged through the cheek plates, ahandle pivotally mounted upon said pivot element and having a lobeprojecting into said recess and provided with an open slot receivingsaid lug or pin, and a spacing collar upon said pivot element betweenthe handle and other cheek plate, the pivot element being composed oftwo sections thread ed together between the handle and spacing collar.

In testimony that I claim the foregoing as my own, I have heretoa'liixed my signature in the presence of two witnesses.
